Problem with Temperature kontroll.

[Vegaaard]

I use virtual device termostat. This work fine but I have problems with temperature 22,5.
When temperature is 23,3 degrees and I sett temperature to 23,5 24, 24,5 osv it will heat.
When temperature is 23,3 degrees and I set temperature to 23, it will cool down but if I sett to 22,5 it starting to heat.
This happen only on 22,5 not 21, 21,5 22, 2
